Dry Eye Clinical Trial - Artificial Tears, Tear Lipids & Tear Film

Status Completed

Clinical Trial Summary

Dry eye disease (DED) is pervasive with some reports estimating over 16 million adults diagnosed in the United States. Currently, artificial tears remain an integral part of managing dry eyes and are mainly used for symptomatic relief. Recent studies have shown there may be therapeutic benefits with regular use of lipid-based artificial tears to improve the structure of the tear film, which may improve tear film stability and provide relief of symptoms. In this study the investigators propose to compare effects on the tear lipid film and its dynamics between 3 lipid based artificial tears and a widely available non-lipid based artificial tear.

Clinical Trial Description

This is a prospective, double-masked, randomized, controlled, parallel-group trial designed to compare the impact of Systane Complete PF lipid-based artificial tears (the Treatment solution under study) on tear lipid layer thickness compared with a non-lipid Control solution, Refresh Relieva PF. Secondarily, the study will compare changes in tear lipid layer thickness, lipid layer uniformity, tear film thinning dynamics, and symptoms between the Treatment solution, the non-lipid Control solution, and 2 other available lipid-based solutions (Active Comparators: Refresh Optive Mega-3 PF and CVS Health Lubricant Eye Drop (PG 0.6%)). The study will include 4 clinic visits, and require 1 week of single-masked run-in with Systane Ultra PF (an over-the-counter non-lipid-based solution) followed by 3 months of study treatment dosing. All subjects will complete a screening interview, then an in-clinic baseline ocular health examination and study eligibility determination followed by dispensing of the Control solution to all subjects for 1 week of run-in. After that week, subjects will be randomized to 1 of the 4 artificial tear solutions and have an in-clinic ocular examination and dispense of the assigned solution to use for 3 months. An in-clinic follow-up examination is completed after 1 month of study solution use, followed by a phone interview at 2 months, and a final in-clinic examination at 3 months post-dispensing. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
